      Check nr in the code below is POSIX read api semantics but is wrong for Windows. This causes the WIndows code to lose error information if read fails.

                      if (!ReadFile(fh->filehandle, addr, chunk, &nr, &overlapped))
                        WT_RET_MSG(session,
                           nr == 0 ? WT_ERROR : __wt_getlasterror(),
                            "%s: handle-read: ReadFile: failed to read %lu "
                            "bytes at offset %" PRIuMAX,
